Why "American" Centrifugals 



Are Most Economical in the Widest 

 Range of Pumping Conditions. 



The reason why "American" Centrifugals are unequaled for economy 

 is that they represent the highest development of the most modern type 

 of pump and there are the best of reasons for this higher development. 



Instead of building a single type of centrifugal and recommend- 

 ing it for every purpose "American" centrifugals are built in over 

 fifty distinct types and every size of every type is carefully tested in 

 our own complete hydraulical laboratory and its efficiency proved 

 before it is permitted to leave our works. 



It must meet our standard of efficiency before it is allowed to 

 leave our works and that is what is making the American trademark 

 famous in pumping machinery. 



"American" centrifugals attain up to 80 per cent mechanical 

 efficiencies and many of our specially designed pumps, installed 

 according to our own specifications, show much higher efficiencies, 

 enabling them to operate against high heads. We have many single 

 stage centrifugals installed operating on over 200 feet heads. 



The low first cost of "American" centrifugals, as compared with 

 old style plunger pumps, combining with their high efficiencies, 

 low cost for attendance and small cost for repairs make them far 

 more economical than any other type of pump in nearly all 

 conditions where all costs are considered. 



Greatest economy in the end is the claim 

 we make for "American" centrifugals and we 

 are ready to prove that claim.
